It looks like Thompson's request worked. The Milwaukee Sheriff Democratic Primary had 108,955 votes while Milwaukee Treasurer Democratic Primary had just 68,181 votes. It could be that the difference in vote totals is simply due to the fact this was a much more contested race. However, before those who support Clarke's policies celebrate too much, they should realize that there is a less sanguine explanation for this 40,774 vote difference between the two races. If it was due to Republicans voting (assuming that some of the Republicans didn't also vote in the treasurer race), Clarke would have been crushed if only Democrats had voted. Indeed, if that were the case, Clarke would have lost 76 to 24 percent. That is quite a reversal from Clarke's previous win in the Democratic primary 4 years ago when he won by 6 percentage points without the benefit of Republican cross overs.The Milwaukee Journal Sentinel discusses the vote breakdown in the city of Milwaukee, which is just a part of the county:

In the city, Clarke did particularly well in predominantly African-American wards in Milwaukee that traditionally have voted heavily Democratic. There, Clarke ran up a 23% lead over Moews, our review of returns from areas with at least 66% black voting population showed. . . .
